Ray tracing works fine on 5.1 but not in 5.3

Hello,
I have Windows 11 on Bootcamp on Mac with eGPU RTX 3060 (Frankenstein I know), however, UE 5.1.1 works very well (Ray Tracing, Path Tracing, ecc…).
Now, UE 5.3.2 has no Ray Tracing at all !!!
In trust I have this configuration: iMacPro with eGPU with two monitors, the eGPU (RTX 3060) pilot the external monitor. In windows I have set the external monitor as Main Monitor. With this configuration, some weeks ago, UE 5.1.1 and UE 5.3.2 works in Ray Tracing very well. Then, I restore (formatted) my Windows partition, reinstalled all the need and UE 5.3.2 only, but NO Ray Tracing. Then I installed UE 5.1.1 and this one works with Ray Tracing ?!?!

Any idea?
